Answer:
<h2>E. 3.95kW</h2>
Explanation:
Power is defined as the rate of workdone.
Power = Workdone/time taken
Given Workdone = Force * distance
Power = Force * distance/time taken
Power = mgd/t (F = mg)
m = mass of the sand in kg
g = acceleration due to gravity in m/s²
d = vertical distance covered in metres
t = time taken in seconds
Given m = 2000kg, d = 12m, t = 1min = 60secs, g = 9.8m/s²
Power = 2000*9.8*12/60
Power = 3920Watts
Minimum rate of power that must be supplied to this machine is 3920Watts or 3.92kW
Answer:
No we cannot
Explanation:
But what causes a ring to appear around the moon? This phenomenon is called a "moon halo." According to the National Weather Service, this ring of light, which is actually an optical illusion, forms around the moon when moonlight refracts off ice crystals in cirrus clouds, high up in the Earth's atmosphere.
B)natural selection
Darwin discovered this idea of natural selection while on a voyage to places such as the Galapagos Islands. Essentially, the idea is that certain animals developed traits that allowed them to survive better than others.
Answer:
Acceleration 
Explanation:
We have given that the force by the motor 
Resistive force by the water 
So net force 
Mass of the boat = 1384.1 kg
According to newton's second law F=Ma, here M is mass and a is acceleration
So
